Be it known that I, WILLIAM ROBJOHN, of the city, county, and State ofNew York, have invented a certain new and useful Improvement on Water orother Liquid-Meters, of which the following is a full, clear, and exactdescription, reference being'had to the accompanying drawing formingpart of this specification, and in \vhich" Figure 1 represents a frontelevation of a meter, constructed according to my improvement.

Figure 2, a partly sectional rear view of the same.

Figure 3, a sectional elevation thereof, parallel and in close proximityto the dial-plate.

Figure 4, a longitudinal view of thc prime mover or first driver to theregistering motion; and

Figure 5, a transverse section of the valvein connection with its box orcase, the direction of the cu'rrent'or'flow of liquid through the meter.

Like letters indicate corresponding parts throughout thescvcrirlfigures.

This invention relates to a meter-for measuring liquids capable of beingregulated to measure large or and passages for changing small andspecified varied quantities; and the natureof the invention consists incertain combinations of mechanism, whereby the meter is madeautomatically to stop on the required quantity being measured, with andprotection sgainst being started without adjustment of the index. Also,in various combinations of mechanism, whereby the general action orworking of the meter is improved,

andleaknge, by dispensing with a stufiing-box to therccipr-ocating'piston of the measuring-cylinder, is avoided.

Referring to the accompanying drawing, A represents the induction pipeof or to the meter, and communicating withs-valve-box, B, so which C isthe cduction pipe, and DI) the pipes or ways to the upper and lower endsof the working or measuring-cylinder E. The valve F is of the butterflyorder, and as it is reciprocated to and fro or oscillated by its shafta, serves to alternate in a rapid and easy manner. the indcution and-.eduction pipes A and C, with the pipes or passages D or-D, to reversethe action of the piston G in the cylinder E, and which form of valve ispreferable to in four-way cock, having contracted openings through itand v controlling said pipes or passages. The piston G has or may haveits rod 6 slotted at or near its top to secure the timely operation, init's reciprocating movement, of a lever, H, that is arranged within awater-tight box or case, I, in communication with the cylinder E at itstop, thereby avoiding the necessity of a striding-box for or to thepiston-rod, and by making the fulcrum-shaft c of, the lever Hot aconical or taper form, where it fits through the box I, securing, by thepressure of the-fluid, a water-tight fit of said shaft. Connected withthe shaft 0 on the outside of the box or case I, is a lever J, to whichis pivoted a rod, K, that is in gear through a slot, d, pin e, andregulating-screw f, to adjust the throw, with a lever, L, reciprocatedintermittently or at intervals by the connections herein described, ator towards thd close of each stroke of the piston G. This lover L isattachedto a fulcrum-shaft, g, and has jointed to it at its outer end arod, {1, which, by means of a crank or arm, 1', connected with thevalve-shaft, reverses the position of the valve F to automatically, orby the operation of the piston G, vary the induction and eduction to'andfrom the upper and lower ends of the measuring cylinder. The gear of therod 1:, with the arm a of the valve, is'a slotted one, so that it is nottill after the lever L has been suddenly shot at or towards the close ofthe piston's stroke, that the valve F is reversed in a sudden andpositivemanner as usual, and well understood to he neccssiiry in otherwater or liquid-meters. This sudden shooting of the lever L is or may beefi'ected as (follows: Fast to said lever is a doubled'nclincd bar orplate, M, forming a culminating point at the centre of its one edge.Bearing against this double-inclined bar is a rollcigj, carried by anarm, is, furnished withprojections or cars l, and pivoted to clever, N,that is borne or pressed forward by a spring, 11', so that in the up ordown motion of the lever-L, and on the culminating point (iicentre ofthe double-inclined bar, passing tlienxial line of the roller 3', whichoccurs when the piston in the measuring-cylinder arrives at the end ofits stroke, the roller, borne forwards by the action of thespring m,presses on the inclined surface or edge of thcb'ar M, to suddenly shootthe lever L, and so reversc the action of the valve E. Connected withthe fulcrum-shaft y, of this ievcr L, is a lover or arm, 0, that carriesat its outer end a slotted bar, 1?, having studs n, n'hichgear, in themanner of s mangle-rack, with a double toe, Q, hung on a shaft orspindle, q, in such manner as that, on each throw, up or down,- of thebar P, by. the operation of the lever L, said toeand its shaft arerotated half a circle, and on the following throvv, up or down, of

. eases 2 the arm P, the motion of the shaft and its toe continued theother half of the circle. This serves-to operate the first driver of theregistering motion or gear, which driver is composed of or by the bodyof the spindle q, slotted at its centre, and formed into teeth or studsr, on either side, and whichgear with a pinion, R, are secured eachthrow to a perfect lock with said pinion, and the double toe adjusted toits proper position by a spring, S. The spindle oi the pinion R carriesa one-toothed disk, T, which gears oncein each revolution with a wheel,U, while thepinion Ritseli', in addition to gearing with the teeth 1' ofthe driver, also gears with a spur-wheei, V. The spindles or shafts ofthe pinion R, and. wheels U and V, carry the indicating fingers a tea,on the dial, and which system of indicators may be multiplied to anydesired extent by the addition of appropriate gear. to effectthe'regi'ster, as is well understood by those acquainted with metersgenerally. The

shaft of the wheel V is made capable of a longitudinal sliding movement,so as to lock or be thrown out of gear with the pinion R. Said wheel maybe thrown out of-gear by means of a spring, 11, pressing on the innerend of its shaft, and be held in gear by' a pin, 10, projecting from therear face of the dial, and bearing against the outer rimof the wheel V,until, during the rotation of the latter, a hole, racemes ,opposite saidpin, when the springv shoots the wheel out of gear, and locks it by theprojection of the pin w through it. By this means the meter may be madeto pass or measure any or a varied specified quantity, and then toautomatically cease, by turning the dial finger-connected with the wheelV to a suitable point or figure on the dial, so as to bring the holes: agiven distance from the pin in, such distance in the circle or rim'ofthe wheel from the pin 10, varying accordingly as it is required toarrest the action of the meter to a small, large, or any intermediatequantity of liquid required to be passed and measured or. registered.-To effect the arrest of the general as well as the registering action ofthe meter by the shooting of the wheel V out of gear and into lock withthe pin- 10, the longitudinal movement of the spindle of said wheel ismade to control a stop-cock, W, on the educ-.-

tion pipe, so that not only is the general action of the meter stoppedby arresting the flow, on the wheel V being shot out of gear and locked,but the cscapeof liquid remaining in the measuring-cylinder arrested,This is accomplished by means of a clutch-lever, y, operatedby thelongitudinally sliding spindleof the wheel V, and connected with arock-shaft, X, that carries una'rm, .1, which, on the wheel V being shotout of gear, acts upon an upper shoulder, a, to a vertical sliding-rod,Y, that,.being depressed, operates, by a lower collar, 6, to trip aspring-borne catch-lever, c, the inner end of which is thereby releasedfrom loclr'or gear, witlra camshaped formation to or of a hand-lever, Z,that controls the stop-cock W,- and which, on being thus thrown out oflock with tho catch-lever. c, is shot back by the action of a spring, A,to close the stop-cock, nor can this stop-cock lever Z be again lockedwith the catch-lever '0 and stop-cock kept, open, till said catch-leveris again put into locking position by the setting of the wheel-V intoregistering gear,when, on throwing the stop-eocklever into lock with thecatch-lever, the meter may again be started and-run.

What' I claim as my inrention, and desire to secureby Letters Patent,is-- 1. The combination of the reciprocating piston G, with its rod 12,measuring-cylinder E, water-tight box or case I, and lever H, all foroperation together and withoutside mechanism, substantially asspecified.

2 The combination, with the shaft 0, ofthelcver H, of the arm J, slottedbar K, lever L, double-inclined bar or plate M, and roller j, foroperation together as herein set forth.

3- The combination of the lever O, slotted bar P, provided with studs 1,in mangled rack-gear, with a double toe, Q, and driver q, furnished withteeth 5', essentially as and for the purpose specified. v

4. The longitudially sliding springdiorne wheel V, having an aperture,1', in combination withs locking stop, w, and geared with a stop-cock,W, for control of the latter substantially as herein set i'orth.

5. The rod Y, operated as described, spring-catch c and stop-cock loveror handle, controlled by aspring,

all for operation together, essentially us and for the purpose orpurposes specified.
